Abstract

A temporary pacemaker combines technologies of the implantable pacemaker, the waterproof watch, with a separate remote-control programming unit that communicates with the pacemaker via IR radiation. An LCD readout on the temporary pacemaker continuously reports on current settings, and is monitored periodically, as well as during the setting process. The programming unit is aimed at an IR sensor on the pacemaker, and its dedicated controls are used for setting, with the aid of prompting messages on its own LCD panel. Battery life is about 6-9 months, while that for the lithium battery in the sealed and sterilizable pacemaker approaches five years.

Claims

1. A remotely programmable temporary pacemaker system for a patient, said pacemaker system comprising;

a. a sealed external pacemaker having coupling means for removably attaching said pacemaker externally to the body of said patient;

b. lead means coupled to said pacemaker for providing percutaneous electrical communication between the heart of said patient and said externally attached pacemaker, wherein said lead means comprises a jack, and wherein said lead means is coupled to said pacemaker by means of a custom connector on said pacemaker configured to receive said jack; and

c. remote programming means for altering pacing parameters of said pacemaker.

2. A remotely programmable temporary pacemaker system for a patient, said pacemaker system comprising:

a. a sealed external pacemaker having coupling means for removably attaching said pacemaker externally to the body of said patient wherein said pacemaker is sufficiently sealed to allow for sterilization by liquid immersion;

b. lead means coupled to said pacemaker for providing percutaneous electrical communication between the heart of said patient and said externally attached pacemaker; and

c. remote programming means for altering pacing parameters of said pacemaker.

3. A remotely programmable temporary pacemaker system for a patient, said pacemaker system comprising:

a. a sealed external pacemaker having coupling means for removably attaching said pacemaker externally to the body of said patient;

b. lead means coupled to said pacemkaer for providing percutaneous electrical communication between the heart of said patient and said externally attached pacemkaer;

c. remote programming means for altering pacing parameters of said pacemaker; and

d. means to display continuously values of the pacing parameters that were most recently set.

4. The temporary pacemaker system of claim 3 including means to display continuously values of the pacing parameters that were most recently set.

5. The temporary pacemaker system of claim 3 including means to display continuously battery-condition indication.

6. A remotely programmable temporary pacemaker system for a patient, said pacemaker system comprising;

a. a sealed external pacemaker having coupling means for removably attaching said pacemaker externally to the body of said patient;

b. lead means coupled to said pacemaker for providing percutaneous electrical communication between the heart of said patient and said externally attached pacemaker;

c. remote programming means for altering pacing parameters of said pacemaker, wherein said remote programming means comprises a hand-held programming unit comprising an LCD display for presenting parameters and values, and a keyboard with dedicated keys for setting each pacing variable.

7. The temporary pacemaker system of claim 6, wherein said remote programming means communicates with the pacemaker by means of infrared radiation.

8. The temporary pacemaker system of claim 6, wherein said remote programming means communicates with the pacemaker by means of radio-frequency radiation.

9. The temporary pacemaker system of claim 6, wherein said remote programming means communicates with the pacemaker by means of visible radiation.

10. The temporary pacemaker system of claim 6, wherein said remote programming comprises an automatic shut-off means to conserve battery life.

11. A remotely programmable temporary pacemaker system for a patient, said pacemaker system comprising:

a. a sealed external pacemaker having coupling means for removably attaching said pacemaker externally to the body of said patient;

b. lead means coupled to said pacemaker for providing percutaneous electrical communication between the heart of said patient and said externally attached pacemaker;

wherein said lead means comprises a jack, and wherein said lead means is coupled to said pacemaker by means of a custom connector on said pacemaker configured to receive said jack; and

c. remote programming means for altering pacing parameters of said pacemaker, wherein said pacemaker has a face with a communication means for communicating with said remote programming means, and means for accepting a pacing lead connector block for connecting said lead means to said pacemaker, said pacing lead connector block including means for engaging into said pacemaker in a specific geometrical relationship.
